GREASE-MEASURING DEVICE.

Application filed March s, 1926. Serial No. 92,846'.

This invention relatesto grease measuring devices, v I

My present invention 18 particularly useful formeasuring the amount of grease which is I I ameter than the interlor of the casing, there dispensed in applying it to automobiles.

An object of my invention is the provision of an efficient grease measuring device.

Viththe foregoing object in View, together vith such other objects and advantages as may subsequently appear, this invention resides in the construction and arrangement of parts hereinafter described and claimed, and

illustrated in the accompanying drawings, in

which;

Figure 1 is a sectional view of the device taken on line 1 -1 of Figure3. I

Figure is a fragmentary plan view of the device shown in Figure 1, the dial being partly broken away. Y

Figure 3 is a plan. view of the device shown in Figure 1, the cover of thedevice andthe superstructure abovev it being removed to show the interior mechanism, and t Figure 4 is a perspective view of a form of the paddle employed in' my device.

Referring to the drawings for a more de-' tailed description thereof, the-numeral 5 in dicates a circular casing comprising a removable cover 6 and a bottom 7 which has an inlet opening 8- and an outlet opening 9, from which respectively extend aninlet pipe 10 and he inlet pipe 10 is reduced at its free end and threaded at that end so that it may be attached to a tube which leads to a supply tank containing grease under air pressure. A paddle wheel 14 has its axle15 journaled in the top 6 and'the bottom 7 of the casing in a manner permitting the paddle wheel to be rotated. The paddle wheel 14 is concentric with the circular casing and extends from the under surface of the cover 6 down to the bottom 7. Paddles 15, illustrated in Figure 4:, are pivotally mounted in the periphery of the wheel and extend to the inner surface of the casing. The paddles 15 are curved and are provided at their inner ends with cylindrical enlargements 17 which fit in recesses in the periphery of the'paddle wheel 14;. The lower,

inner ends of the enlargements 17 are cut away, as indicated by the numeral 19 in Figure 4.

The periphery of the paddle wheel 14s is notched adjacent each paddle so that the pivoted paddles when turned in towards the wheel, as hereinafterdescribed, form a con 'tinuation of the arcuate periphery ,ofthe wheel, as shownby a turned in paddle illus trated in Figure 3. These notches are desig.

nated by the numerallt V The paddle wheel 14:, being smaller in diis a circular channel 21 between the Wheel and. the casing. Beyond the outlet opening 9'is.. disposed a plate 22 pivotally connected to the casing at 23, The plate 22 is adapted to close the passageway 21 if desired, so that all the;

. grease may be forced into the outlet opening 9. If, however, it is desired to allowsome of the grease topass the outlet opening'and to wheel 14 rotates, the pivoted paddles or blades 15, as they come-in contact with the plate 22, are turned in by the plate toward the Wheel.

in order to allow the. curved blades 15 to be turned in, so as to form a continuation of the periphery of the wheel and not be prevented The grease of course fills the notches 1 1 and by the grease from assuming such position,

the notches 1d are cut so as to provide spaces '14 between the turned in paddles and the inner boundaries of the notches.

The paddle wheel 14 and the blades attached thereto are of'course rotated by the incoming grease which is under pressure. After the turned in paddles or blades 15 pass the plate22, the notched portions 19 of the cylindrical enlargements 17 of the blades. come into contact with an arcuate vertical plate 30 which rises from the bottom of the casing, and are turned by such contact back into their normal position in which they extend to the inner periphery of the casing. The cover 6 of the casing, which is substantially air-tight, is removably secured to the main portion of thecasing by means of screws 32.

dispensed from the device. Means are prollu I gear wheel 42 and the dial plate 35.

s which is secured to the sleeve 37.

vided whereby the turning of the Wheel 14 turns the indicator 36, and such means are herein shown as comprising a train of gears adapted to be actuated by the wheel and to turn a sleeve 37 on which the indicator 36 is mounted,the sleeve 37 being 'revolvable on the upper end of the axle 15. The gear train comprises a gear wheel 38 keyed to the axle 15 of the wheel 14; The wheel 38 meshes with a gear 39, fixed to a pin 40, which is journaled in the cover 6 and the dial plate 35. A gear Wheel 41 is also mounted on the pin 40-and engages with a gear Wheel 42 A helical spring 43 encircles the sleeve 37 between the This spring keeps the gear wheel 42 in position to mesh with the gear wheel 41. When it is desired to reset the indicator 36, the sleeve 37 may be pulled.upwardly to disengage the wheel 42 from, the wheel 41, the spring 43 yielding'to'the upward pull on the sleeve 87.

It will be understood that the ratios of the various gears of the above 'i'nentioned gear train may be changed to cause the indicator 36 to move over any desired number of degrees off the dial for each revolution of the paddle wheel-14. The size of the device may be made to deliver any desired amount of grease for each revolution of the wheel 14.

In operating the measurin device, it is adapted to be attached through the pipe 10 to 'a container holding grease under pressure,

suclr'jorexample as air pressure. The grease moves through the pipe 10 and into the-body ofthe measuring device through an aperture 8 in the bottom thereof, and continues its 'mot'ion' through the circular channel 21 and turns the paddle wheel 14 which bears against the paddles 15. -'Grease leaves the body of the device through the outlet opening 9, and

passes through the pipe 1 2, which may be attached to a tube having a nozzle at the end thereof.

I11 dispensing the grease to a customer, the

indicator 86 should preferably be at a preon the sleeve 37, so that the gear 42 is disengaged from the gear 41, wherebythe indicator may be rotated without turning the paddle wheel 14. It is of course understood that the device isto be calibrated inorder that the indicator may accurately indicate the amount of grease dispensed.

lVhile I have described one embodiment of myin-vention, modifications thereof may be readily devised'without departing from the spirit of my invention, and it is tobe understood thatsuch modifications come within the scope of the appended claim.

I claim: r A device of the character described comprising a casinghaving inlet and outlet openings, a rotatable paddle wheel in said casing and paddles pivoted'tosaid wheel and extend ing from the periphery thereof tosaid ca"s ing and adjustable'means in said casing beyond'sa'id outlet opening for varying the area of the passage between said casing and said wheel, said adjustable means comprising a plate pivotally mounted in said casing, -a screw pivotally connected to saidplate, said screw threadedly engaging said casing, and extending exteriorly thereof whereby the position of said plate may be adjusted'exteriorly of the casing.
